Please use minitab, and show the steps to get to the solution.Meaning: Go to Stat, basic statistics, etc, etc.
Forty sewage samples a waste water treatment plant werecollected from a recent EPA report. The ppm of suspended solids ineach specimen is presented in the following table. (a) Examinedescriptive statistics of the mean, median, standard deviation,first quartile, third quartile, minimum value, and maximum value.What do these statistics indicate about the shape of the populationdistribution? (b) Create a histogram with binning center points at30, 40, 50, 60, 70, 80, 90, and 100. What does the shape of thehistogram tell of about the shape of the population distribution?(c) Construct a normal probability plot, a lognormal probabilityplot, and a Weibull probability plot of these data. Allow Minitabto estimate the best fit parameters for each distribution. Based onthe plots and associated Anderson-Darling (AD) fit statistics,identify which distribution seems to be the best fit model at ? =0.05 for suspended solid material (ppm) in water. 59.4 44.3 55.439.9 50.8 45.9 53.4 80.7 68.8 40.3 49.5 64.5 48.4 82.4 33.6 75.337.4 50.6 62.7 56.2 86.8 42.7 44.2 30.7 43.4 50.9 44.8 69.1 102.253.1 68.9 43.6 59.1 79.6 90.7 51.6 71.2 55.3 59.6 50.8
